Brendan Smith

Brendan Smith has spent over 15 years knee-deep in cybersecurity, chasing down malware from the gritty reverse-engineering of old-school trojans all the way to wrangling full-blown incident responses for small-to-medium businesses that couldn’t afford a full-blown breach. Over at Gridinsoft, he’s the guy piecing together those double-checked guides on nasty stuff like AsyncRAT ransomware—take last year, for instance, when his breakdowns caught more than 200 sneaky variants right in live scans, knocking user cleanup jobs down by a solid 40% and saving folks hours of headache.
